Suppose the total benefit derived from a given decision, q, is b(q) = 20q – 2q2 and the corresponding total cost is c(q) = 4 + 2q2, so that mb(q) = 20 – 4q and mc(q) = 4q. instruction: use a negative sign where appropriate. a. what is total benefit when q = 2? q = 10? when q = 2: 32 when q = 10: 150 b. what is marginal benefit when q = 2? q = 10? when q = 2: 12 when q = 10: c. what level of q maximizes total benefit? 5 d. what is total cost when q = 2? q = 10? when q = 2: 12 when q = 10: e. what is marginal cost when q = 2? q = 10? when q = 2: 8 when q = 10: f. what level of q minimizes total cost? 0 g. what level of q maximizes net benefits? 2.5 check my work
